There are several types of air cleaners that fit velocity stacks...

There are the "tea strainer' types that fit over the lip with two mesh screens sandwiching a filter element.......there are "weber" type air filters that fit over one or both of the throttle bodies (without the actual velocity stack).....There are K&N filters that snug to the outside lip of the velocity stack...and there are air filters that enclose all the velocity stacks in one unit.

First....How much vertical clearance between the top of the velocity stack and the underside of your hood (hood clearance)?

Second....Are you running 8 stacks (independent runners)....4 weber carbs...or something else?

Third....How much air does your engine require to breathe correctly...What are the CFM requirements of air intake?

Fourth...do you want a show look or just something functional?
